Hi, I suffer from an S4 problem with XHCI of PantherPoint with rc6. Coming up from S4 I get errors: [ 250.912198] xhci_hcd 0000:00:14.0: setting latency timer to 64 [ 250.912210] usb usb3: root hub lost power or was reset [ 250.912212] usb usb4: root hub lost power or was reset [ 250.912256] xhci_hcd 0000:00:14.0: Slot 1 endpoint 2 not removed from BW list!

It looks like the bandwidth change when going down to S4 is not accounted for. Do you have any ideas?
